| titleOfInvention | Phthalide compound and recording material using the compound |
| abstract | (57) [Summary] [Structure] A phthalide compound represented by the general formula [Chemical Formula 1], And a recording material containing at least one phthalide compound represented by [Chemical formula 1] as a colorless or light-colored dye precursor. [Effect] The obtained recording material can be sufficiently applied to an optical character reader having a reading wavelength range in the infrared region, and the obtained recorded image is excellent in light resistance and can be exposed to light for a long time. It does not fade, has excellent shelf life, and has an extremely high commercial value. |
